Brief Report: Age-Disparate Relationships and HIV Prevalence Among Never Married Women in Rakai, Uganda

Adverse childhood experiences, HIV and sexual risk behaviors - Five sub-Saharan countries, 2018-2020

BACKGROUND

Adverse childhood experiences (ACEs) have been shown to have negative, lasting effects on health including increasing the likelihood of engaging in sexual risk behaviors.

OBJECTIVE

This study aimed to identify associations between exposures to ACEs and sexual risk behaviors and HIV service utilization among young people.

PARTICIPANTS AND SETTING

A sample of 8023 sexually active young people (19-24 year olds) from five sub-Saharan African countries participated Violence Against Children and Youth Surveys (VACS).

METHODS

Descriptive analysis of demographic variables, individual ACEs, cumulative ACEs, sexual risk behaviors, HIV testing, antiretroviral treatment (ART) and Antenatal Care (ANC) attendance were completed. Bivariate and multivariable logistic regression analyses were conducted to assess the associations between both individual and cumulative ACEs, sexual HIV risk behaviors, and service utilization while controlling for important covariates such as demographic, having ever been pregnant, had an STI, and used contraception.

RESULTS

Exposure to three or more ACEs was higher among males (26.1 %) compared to females (21.3 %); p = 0.003. The most prominent sexual risk behavior for females was having sexual partners who were at least 5 years older (45.7 % compared to males 3.7 %; p < 0.0001) whereas in males it was no or infrequent condom use (45.3 % compared to females 30.1 %; p < 0.0001). Males and females exposed to childhood sexual violence had seven and four times the odds of engaging in transactional sex (aOR = 7.34, 95 % CI: [3.5-15.0]) and (aOR =3.75, 95 % CI: [2.3-6.2], respectively. Females exposed to three or more ACEs were four times more likely to engage in transactional sex (aOR = 4.85, 95 %, CI: [1.6-14.4]) compared to those who did not experience any ACEs. Males exposed to three or more ACEs were two times more likely to engage in early sexual debut (aOR = 2.2, 95 % CI: [1.3-3.4]),]) compared to those who did not experience any ACEs. Females who had witnessed IPV or violence in the community had significantly higher odds of getting tested for HIV (aOR = 2.16, 95 % CI: [1.63-2.87]) and (aOR = 1.36, 95 % CI: [1.03-1.81]), respectively.

CONCLUSIONS

This study demonstrated that experiencing ACEs during childhood is associated with higher HIV risk behaviors in sub-Saharan Africa (SSA) with unique differences between males and females.

Age-disparate and intergenerational sex partnerships and HIV: the role of gender norms among adolescent girls and young women in Malawi

BACKGROUND

Age-mixing (age-disparate [5-9 years difference] and intergenerational [≥ 10 years difference]) partnerships are hypothesized drivers of HIV in adolescent girls and young women (AGYW; 15-24 years). These partnerships are often associated with increased gender inequities which undermine women's agency and assertiveness. We assessed whether age-mixing partnerships were associated with HIV in Malawi and if endorsement of inequitable gender norms modifies this relationship.

METHODS

We analyzed data from the Malawi Population-based HIV Impact Assessment, a nationally representative household survey conducted in 2015-2016. Participants underwent HIV testing and completed questionnaires related to actively endorsed gender norms and sexual risk behavior. We used multivariate logistic regression and multiplicative interaction to assess associations among AGYW who reported the age of their primary sex partner from the last year.

RESULTS

The analysis included 1,958 AGYW (mean age = 19.9 years, SD = 0.1), 459 (23.4%) and 131 (6.7%) of whom reported age-disparate and intergenerational partnerships, respectively. AGYW in age-mixing partnerships accounted for 13% of all AGYW and were older, more likely to reside in urban areas, to be married or cohabitating with a partner, and to have engaged in riskier sexual behavior compared with AGYW in age-concordant partnerships (p < 0.05). HIV prevalence among AGYW in age-disparate and intergenerational partnerships was 6.1% and 11.9%, respectively, compared with 3.2% in age-concordant partnerships (p < 0.001). After adjusting for residence, age, education, employment, wealth quintile, and ever been married or cohabitated as married, AGYW in age-disparate and intergenerational partnerships had 1.9 (95% CI: 1.1-3.5) and 3.4 (95% CI: 1.6-7.2) greater odds of HIV, respectively, compared with AGYW in age-concordant partnerships. Among the 614 (31% of the study group) who endorsed inequitable gender norms, AGYW in age-disparate and intergenerational partnerships had 3.5 (95% CI: 1.1-11.8) and 6.4 (95% CI: 1.5-27.8) greater odds of HIV, respectively, compared with AGYW in age-concordant partnerships.

CONCLUSIONS

In this Malawi general population survey, age-mixing partnerships were associated with increased odds of HIV among AGYW. These findings highlight inequitable gender norms as a potential focus for HIV prevention and could inform interventions targeting structural, cultural, and social constraints of this key group.

Older men, younger women: blesser-blessee relationships among university students in Durban, South Africa

In sub-Saharan Africa, sexual relationships between younger women and older men have been shown to pose a risk of HIV transmission. In South Africa, there has been growing interest in blesser-blessee relationships. This study explores perceptions of these relationships among university students in Durban, South Africa. The study draws on 15 in-depth interviews with students. Participants suggest that older men engage in these relationships for sexual gratification and younger women do so for monetary or material gain. Interviews revealed that participants believed that these relationships are common with both men and women engaging in them and putting themselves at risk of HIV infection. It is imperative to explore the context and motivation for these relationships because of their broader social and health implications. In addition, greater effort should be geared towards addressing the underlying factors that facilitate blesser-blessee relationships.

Sexual partnership concurrency and age disparities associated with sexually transmitted infection and risk behavior in rural communities in Kenya and Uganda

OBJECTIVES

We examined sex-specific associations of partner age disparity and relationship concurrency with Neisseria gonorrhoeae and/or Chlamydia trachomatis (NG/CT) infection, higher-risk relationships, and condom use as proxies for HIV risk.

METHODS

Data were collected in 2016 from 2179 adults in 12 communities in Uganda and Kenya. Logistic regression models examined associations of age disparity and relationship concurrency with NG/CT infection, condom use, and higher-risk (commercial sex and other higher-risk) relationships in the past 6 months, controlling for covariates.

RESULTS

Partner age and relationship concurrency were associated with NG/CT infection in women but not men. Relative to women in age-disparate relationships, women in both age-disparate and age-homogeneous relationships had higher odds of NG/CT infection (adjusted odds ratio [aOR]=3.82, 95% confidence interval [CI]: 1.46-9.98). Among men and women, partnership concurrency was associated with higher-risk partnerships. In addition, relative to those with a single age-homogeneous partner, those with concurrent age-homogeneous partners had higher odds of condom use (men: aOR=2.85, 95% CI: 1.89-4.31; women: aOR=2.99, 95% CI: 1.52-5.89). Concurrent age-disparate partnerships were associated with condom use among men only (aOR=4.02, 95% CI: 2.54-6.37).

CONCLUSION

Findings underscore the importance of targeted HIV prevention efforts for couples in age-disparate and concurrent relationships.

Adolescent girls' perceived readiness for sex in Central Uganda - liminal transitions and implications for sexual and reproductive health interventions

Young women in Uganda are at risk of negative sexual and reproductive health outcomes, in part because of sex with older men. Theoretically grounded in the concept of liminality, this paper examines perceived markers of adolescent girls' suitability for sexual activity. In 2014, we conducted 19 focus group discussions and 44 in-depth interviews in two communities in Uganda. Interviews were conducted using a semi-structured tool, audio-recorded and transcribed verbatim. Interviews examined markers of transition between childhood, adolescence and adulthood and how these were seen as relating to girls' perceived readiness for sex. Analysis was thematic. Pre-liminal status was most often accorded to childhood. Sex with a child was strongly condemned. Physical changes during puberty and children's increasing responsibility, autonomy and awakening sexuality reflected a liminal stage during which girls and young women were not necessarily seen as children and were increasingly described as suitable for sex. Being over 18, leaving home, and occupying 'adult' spaces reflected post-liminal status and perceived appropriateness for sexual activity including for girls under the age of 18. Interventions that seek to prevent early sexual debut and sexual activity with older men have the potential to reduce sexual and reproductive health risks.

Trends and Correlates of Age-Disparate Sexual Partnerships in the United States: The National Health and Nutrition Examination Surveys

ABSTRACT

This national survey demonstrates age-disparate (≥5 years; AD-5) sexual partnerships remain common among males and females aged 20 to 29 years in the United States (2005-2016). Females reported more older AD-5 partners, and males reported more younger AD-5 partners. Having AD-5 partners was associated with greater lifetime and recent number of sexual partners.

The determinants and impacts of age-disparate relationships on women in Zimbabwe: A life course perspective

Age-disparate relationships (ADR) with older men have been studied mostly in the context of HIV and found to be associated with increased HIV prevalence among young women in sub-Saharan Africa. Less is known about the impact of ADR on the broader life course of women. The objectives of this study are to identify the factors associated with being in ADR and estimate the association between ADR and a set of life outcomes in Manicaland, Zimbabwe. We used data from a general population open-cohort survey from 1998 to 2013 in Manicaland. We applied binary logistic regression models to estimate the odds ratios for association between socio-demographic determinants and ADR and multinomial logistic regression models to estimate the association between ADR and women's life outcomes. We found that women with less education, younger age at first sex and first marriage were more likely to be in ADR, and women in ADR have male partners with less education and less skilled employment. In terms of life and relationship outcomes, women in ADR had mostly negative life outcomes compared to women not in ADR. Future policies and research on ADR in women should reflect these complexities and study a wider range of life outcomes, beyond the commonly studied narrower topics such as HIV.

HIV-1 Entry and Prospects for Protecting against Infection

Human Immunodeficiency Virus type-1 (HIV-1) establishes a latent viral reservoir soon after infection, which poses a major challenge for drug treatment and curative strategies. Many efforts are therefore focused on blocking infection. To this end, both viral and host factors relevant to the onset of infection need to be considered. Given that HIV-1 is most often transmitted mucosally, strategies designed to protect against infection need to be effective at mucosal portals of entry. These strategies need to contend also with cell-free and cell-associated transmitted/founder (T/F) virus forms; both can initiate and establish infection. This review will discuss how insight from the current model of HIV-1 mucosal transmission and cell entry has highlighted challenges in developing effective strategies to prevent infection. First, we examine key viral and host factors that play a role in transmission and infection. We then discuss preventive strategies based on antibody-mediated protection, with emphasis on targeting T/F viruses and mucosal immunity. Lastly, we review treatment strategies targeting viral entry, with focus on the most clinically advanced entry inhibitors.

Risk of HIV infection among adolescent girls and young women in age-disparate relationships in sub-Saharan Africa

OBJECTIVE

To determine the association between age-disparate relationships and risk of HIV infection among adolescent girls and young women (AGYW) aged 15-24 years.

DESIGN

Systematic review and meta-analysis of published studies until January 5, 2020 in sub Saharan Africa (SSA).

METHODS

We searched several electronic databases, grey literature, and hand searched reference list of included studies to identify eligible studies for data abstraction. We assessed the quality of included studies using Newcastle-Ottawa Scale for nonrandomized studies. The DerSimonian-Laird random effects model was used to pool the overall results using risk ratios (RR), presented in a forest plot with 95% confidence interval (CI) and predictive interval. Heterogeneity was assessed with Cochrane's Q-test and quantified with I values. Publication bias was checked with funnel plots and Egger's test.

RESULTS

We included 24 studies with an overall sample size of 33 390. Data show that age-disparate relationships were significantly associated with unprotected sexual intercourse (pooled RR, 1.57; 95% CI, 1.34-1.83; 95% predictive interval, 1.22-2.02), and higher risk for HIV infection (pooled RR, 1.39; 95 CI, 1.21-1.60; 95% predictive interval, 0.80-2.42). Studies included in pooling risk of unprotected sexual intercourse were largely homogeneous (I-value= 0.0, P = 0.79) whereas those for HIV infection were heterogeneous (I- value = 89.0%, P < 0.01). We found no publication bias and no study influenced the meta-analytic results.

CONCLUSION

Age-disparate relationships among AGYW are associated with increased risk of unprotected sexual intercourse and HIV infection in SSA. HIV prevention interventions should target this sub-population.

Trends in HIV Prevention, Treatment, and Incidence in a Hyperendemic Area of KwaZulu-Natal, South Africa

IMPORTANCE

In Africa, the persistently high HIV incidence rate among young women is the major obstacle to achieving the goal of epidemic control.

OBJECTIVE

To determine trends in coverage of HIV prevention and treatment programs and HIV incidence.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study consisted of 2 sequential, community-based longitudinal studies performed in the Vulindlela and Greater Edendale area in KwaZulu-Natal, South Africa. Participants enrolled from June 11, 2014, to June 22, 2015 (2014 survey), with a single follow-up visit from June 24, 2016, to April 3, 2017 (2016 cohort), or enrolled from July 8, 2015, to June 7, 2016 (2015 survey), with a single follow-up visit from November 7, 2016, to August 30, 2017 (2017 cohort). Men and women aged 15 to 49 years were enrolled in the 2014 and 2015 surveys, and HIV-seronegative participants aged 15 to 35 years were followed up in the 2016 and 2017 cohorts. Analysis was conducted from January 1 through December 31, 2018.

EXPOSURES

HIV prevention and treatment programs in a real-world, nontrial setting.

MAIN OUTCOMES AND MEASURES

Trends in sex- and age-specific HIV incidence rates, condom use, voluntary medical male circumcision, knowledge of HIV-seropositive status, uptake of antiretroviral therapy, and viral suppression.

RESULTS

A total of 9812 participants (6265 women [63.9%]; median age, 27 years [interquartile range, 20-36 years]) from 11 289 households were enrolled in the 2014 survey, and 10 236 participants (6341 women [61.9%]; median age, 27 years [interquartile range, 20-36 years]) from 12 247 households were enrolled in the 2015 survey. Of these, 3536 of 4539 (annual retention rate of 86.7%) completed follow-up in the 2016 cohort, and 3907 of 5307 (annual retention rate of 81.4%) completed follow-up in the 2017 cohort. From 2014 to 2015, condom use with last sex partner decreased by 10% from 24.0% (n = 644 of 3547) to 21.6% (n = 728 of 3895; P = .12) in men and by 17% from 19.6% (n = 1039 of 6265) to 16.2% (n = 871 of 6341; P = .002) in women. Voluntary medical male circumcision increased by 13% from 31.9% (1102 of 3547) to 36.1% (n = 1472 of 3895); P = .007) in men, and the proportion of women reporting that their partner was circumcised increased by 35% from 35.7% (n = 1695 of 4766) to 48.2% (n = 2519 of 5207; P < .001). Knowledge of HIV-seropositive status increased by 21% from 51.8% (n = 504 of 3547) to 62.9% (n = 570 of 3895; P < .001) in men and by 14% from 64.6% (n = 1833 of 6265) to 73.4% (n = 2182 of 6341; P < .001) in women. Use of antiretroviral therapy increased by 32% from 36.7% (n = 341 of 3547) to 48.6% (n = 432 of 3895; P < .001) in men and by 29% from 45.6% (n = 1251 of 6265) to 58.8% (n = 1743 of 6341; P < .001) in women; HIV viral suppression increased by 20% from 41.9% (n = 401 of 3547) to 50.3% (n = 456 of 3895; P = .005) in men and by 13% from 54.8% (n = 1547 of 6265) to 61.9% (n = 1828 of 6341; P < .001) in women. Incidence of HIV declined in women aged 15 to 19 years from 4.63 (95% CI, 3.29-6.52) to 2.74 (95% CI, 1.84-4.09) per 100 person-years (P = .04) but declined marginally or remained unchanged among men and women in other age groups.

CONCLUSIONS AND RELEVANCE

This study showed a significant decline in HIV incidence in young women; however, to further reduce HIV incidence, HIV prevention and treatment program coverage must be intensified and scaled up.

Integration of HIV-Sexual Reproductive Health Services for Young People and the Barriers at Public Health Facilities in Mbarara Municipality, Southwestern Uganda: A Qualitative Assessment

Background

Sexual and Reproductive Health (SRH) and HIV risk behaviors for young people are intertwined. This rationalizes the need for integration of HIV and SRH services within the health care system, especially in countries with high HIV burden. In this study, we explored the current status of HIV-SRH integration for young people and barriers of integration from different stakeholders at public health facilities in Mbarara Municipality, southwestern Uganda.

Methods

We conducted an exploratory qualitative study at public health facilities in Mbarara district of southwestern Uganda. Data were collected among young people (n=48), health care providers (n=63), and key informants (n=11). We used in-depth interviews and focus group discussions to collect the data. Coding and analysis of qualitative data were done using Atlas.ti.

Results

Overall there was no differentiation of HIV-SRH services between adults and young people. Integration of HIV-SRH services was reported at all facility levels; however, there was poor differentiation of services for the young persons and adults. Integrated HIV and SRH services for young people were acknowledged to improve access to information and risk perception, improve continuity of care, and reduce cost of services and would also lead to improved client-health worker relationships. The potential barriers to achieving HIV-SRH integration included individual provider characteristics like lack of training and attitudes, generic health system challenges like low staffing levels, poor infrastructure with lack of space and privacy to deliver these services. At the policy level vertical programing and unclear policies and guidelines were identified as challenges.

Conclusion

Our study shows integration of HIV and SRH services exists in general but services for adults and young people are blended or poorly differentiated. Significant health system barriers need to be overcome to achieve differentiation of the services for young people and adults.
